ARDUINO RF TRANSMITTER

 ARDUINO RF TRANSMITTER CIRCUIT                This is a simple arduino uno based simple wireless RF transmitter project.The transmitter frequency can be changed by simply changing default frequency values in the arduino program.The range the transmission is a few 100 meters.This is quiet normal for such a low power transmitter.The power output of this transmitter is a few milliwatts may be around 100mw.The power output of the transmitter can be increased using RF power amplifiers.The radio transmission can be heard with a radio.Tune the radio to the frequency same as that of transmitter's frequency.The frequency can be in between 32khz-8Mhz in range.The antenna wire is taken from digital pin 11 of arduino. PROGRAM :  The program for this project is linked below.Check out DOWNLOAD HERE COMPONENTS USED :  Arduino Uno/Arduino Nano ANTENNA SPECIFICATION :  24 swg 1 meter length single core wire  PROJECT LIST :  * ...

WIRELESS AC POWER DETECTOR CIRCUIT DIAGRAM SIMPLE

Image
               WIRELESS AC POWER  DETECTOR CIRCUIT DIAGRAM    This is a simple wireless ac power detector circuit which detects the presence of ac supply in our home.The project uses cd4060 ic to detect the presence of magnetic field at the pin 11 which consists of a coil of 5 turns.We can take any long wire instead,as no specefic coil is needed just a piece of wire is enough.The sensed signal is amplified at pin 7 of ic and the output is given to bc547 transistor at the final stage to drive the buzzer.A 22 ohms resistor is used to limit the current across the buzzer.An led indicator is placed to same pin to visualise the presence of output.          The principle behind is the presence of mutual induction.For an y  piece of wire,whenever current is flown through the wire will induce a small voltage across the wire.We know that our home wires have high voltage even if its not a coil form,but the vo...

WIRELESS POWER TRANSFER

 WIRELESS POWER TRANSFER                Wireless power transfer is the electrical energ y  transmission without using wires. The principle used is simple mutual induction and this was discovered by Nickolas Tesla back in years.He discovered that magic happens when some coil of wires is placed near a power source of AC which he was experimenting with the winding coil wires.From this he discovered and strongly belived that AC power source can go wirelessly to greater extend.But his knowledge on experiments is limited as we knows now that air is a not a good conductor of electricity,as even radio signal will fade to an extend. Eventhough,it has a larger application like low power charging stations,wireless phone charger etc..Now a days all are becoming wireless.There were times we use DC current in homes,But the DC power is impratical for a distant wired power transmission.The discover y of AC b y Tesla  and its flexibilit y to co...
